LLVM change dfbd76bda01e removed separate remark support entirely, but
it turns out we can just drop the parameter and everything appears to
work fine.
Fixes 146912 as far as I can tell (the test passes.)

tests/run-make/crate-loading: Rename source files for clarity
For rust-lang/rust#146874 I originally tried to extend the existing test **tests/run-make/crate-loading**. That didn't work out since adding a re-export of the entire crate significantly changes the emitted error messsage.
I did put some effort into making that test easier to understand however, by renaming its files. (Since I was confused myself at first.) Let's save some time for future devs by doing just the renames.
Further cleanups are possible, but that will change the blessed output, so let's not do that right now.
r? ```@jieyouxu``` since you have the context of rust-lang/rust#146874

Linker-plugin-based LTO: update list of good combinations (inc. beta + nightly)
This PR updates the list of good combinations of Rust toolchains and LLVM releases for linker-plugin-based LTO
Related to first question in https://users.rust-lang.org/t/questions-regarding-linker-plugin-based-lto/134070

add private module override re-export test
- Closes rust-lang/rust#60926
Added a new test to check that `rustdoc` does not create links to `m2` in the crate root when `pub use m1::*` is overrided by `use crate::m1::m2`.

mbe: Simplifications and refactoring
A few simplifications and refactors in advance of other work.
Macro metavariable expressions were using `Ident::as_str` and doing string
comparisons; I converted them to use symbols.
I factored out a function for transcribing a `ParseNtResult`, which will help
separate the evaluation and transcription of future macro metavariable
expressions.

Fix a dangling reference in `rustc_thread_pool`
This diverged from `rayon` in rust-lang/rust#142384, where a cleanup commit turned the matched `worker_index` into a reference, which is read _after_ the `set` that may kill it. I've moved that read beforehand, and I hope the new comments will emphasize the subtlety of this unsafe code.
Hopefully fixes rust-lang/rust#146677.

[win] Use find-msvc-tools instead of cc to find the linker and rc on Windows
`find-msvc-tools` was factored out from `cc` to allow updating the use in `rustc_codegen_ssa` (finding the linker when running the Rust compiler) and `rustc_windows_rc` (finding the Windows Resource Compiler when running the Rust compiler) to be separate from the use in `rustc_llvm` (building LLVM as part of building the Rust compiler).

test: Use SVG for terminal url test
I came across the test for `-Zterminal-urls` and found its output a bit hard to read. So, I decided to switch it to an SVG test, as I found it easier to differentiate the link and link text.
Note: `anstyle-svg` needed to be upgraded to at least `0.1.8` to support links in SVGs, so I went ahead and upgraded it to the latest version (`0.1.11`).

Fix uses of "adaptor"
These docs are in en_US, so "adapter" is the correct spelling (and indeed used in the next line.)
A second commit comes along for the ride to fix other instances in non-rustdoc comments.

GCS support was added to GCC in version 15, thus the rmake test for this
patch requires GCC15
Similarly, the ubuntu version is updated so the newer clang version is
available, and/or GCC15 is the default.

Fix "Replace match with if let" not to trigger when invalid transformations occur

(This re-introduces a reduced access to a couple of previously public fields on `InferenceResult`)

Emit `#[rustc_allocator]` etc. attributes on the functions generated
by the `#[global_allocator]` macro, which will emit LLVM attributes
like `"alloc-family"`. If the module with the global allocator
participates in LTO, this ensures that the attributes typically
emitted on the allocator declarations are not lost if the
definition is imported.

Add panic=immediate-abort
MCP: https://github.com/rust-lang/compiler-team/issues/909
This adds a new panic strategy, `-Cpanic=immediate-abort`. This panic strategy essentially just codifies use of `-Zbuild-std-features=panic_immediate_abort`. This PR is intended to just set up infrastructure, and while it will change how the compiler is invoked for users of the feature, there should be no other impacts.
In many parts of the compiler, `PanicStrategy::ImmediateAbort` behaves just like `PanicStrategy::Abort`, because actually most parts of the compiler just mean to ask "can this unwind?" so I've added a helper function so we can say `sess.panic_strategy().unwinds()`.
The panic and unwind strategies have some level of compatibility, which mostly means that we can pre-compile the sysroot with unwinding panics then the sysroot can be linked with aborting panics later. The immediate-abort strategy is all-or-nothing, enforced by `compiler/rustc_metadata/src/dependency_format.rs` and this is tested for in `tests/ui/panic-runtime/`. We could _technically_ be more compatible with the other panic strategies, but immediately-aborting panics primarily exist for users who want to eliminate all the code size responsible for the panic runtime. I'm open to other use cases if people want to present them, but not right now. This PR is already large.
`-Cpanic=immediate-abort` sets both `cfg(panic = "immediate-abort")` _and_ `cfg(panic = "abort")`. bjorn3 pointed out that people may be checking for the abort cfg to ask if panics will unwind, and also the sysroot feature this is replacing used to require `-Cpanic=abort` so this seems like a good back-compat step. At least for the moment. Unclear if this is a good idea indefinitely. I can imagine this being confusing.
The changes to the standard library attributes are purely mechanical. Apart from that, I removed an `unsafe` we haven't needed for a while since the `abort` intrinsic became safe, and I've added a helpful diagnostic for people trying to use the old feature.
To test that `-Cpanic=immediate-abort` conflicts with other panic strategies, I've beefed up the core-stubs infrastructure a bit. There is now a separate attribute to set flags on it.
I've added a test that this produces the desired codegen, called `tests/run-make-cargo/panic-immediate-abort-codegen/` and also a separate run-make-cargo test that checks that we can build a binary.
